Can someone tell me what the LED's on your CZ unit do when hooked up?

I get 2 amber lights and the one on the right goes blinky blinky while the left one is solid.

It does this at idle, regardless of which way the switch is facing.

 

The switch shouldn't have any effect on the lights. The lights will change when you rev. the engine past about 2K RPM. That's when the unit starts to read from its' map and modify the A/F and timing.
